Code Description

ICD-10 F18.251 is a billable code used to indicate a diagnosis of inhalant dependence with inhalant-induced psychotic disorder with hallucinations.

Key Diagnostic Point:

F18.251 refers to a condition characterized by a dependence on inhalants, which are substances that produce chemical vapors that can be inhaled to induce psychoactive effects. This code specifically denotes the presence of inhalant-induced psychotic disorder, which manifests as hallucinations. Patients with this condition may experience significant impairment in social, occupational, or other important areas of functioning due to their substance use. The inhalants can include a variety of substances such as glue, paint thinners, and nitrous oxide. The psychotic symptoms can include visual or auditory hallucinations, delusions, and disorganized thinking. Treatment typically involves a combination of detoxification, counseling, and support groups, as well as addressing any co-occurring mental health disorders. The chronic use of inhalants can lead to severe health complications, including neurological damage, which necessitates a comprehensive treatment approach.
